We open out main presents after lunch. The kids have stockings with little pressies on their beds to open as soon as they wake up. But the big presents sit under the tree until after lunch. It started when I was a child and we always had a posh breakfast on Christmas morning - proper laid table with cloth and the best china etc, home-made milk rolls and home-made plum jam and real coffee. And then church and probably people back for a sherry before lunch. So no time before I suppose. It also means that it all lasts a bit longer. I love christmas with my kids but I do miss the slightly more special way we did christas as a child - everyone dressed up and everything done a bit more formally. DH wouldn't stand for it though .
In all my 41 years I've only met one other family that wait till after lunch.
Anyone else?
